DETAILED DESCRIPTION

A removable shelter and elements for constructing a removable shelter is described below.

In at least one embodiment, the rib frame is constructed using a series of brackets and tubular members. Each bracket has a variable angle member capable of receiving a tubular member at a variable angle. Each bracket is attached directly to a base frame.

In at least one embodiment, the base frame is placed over the perimeter of a surface that is to be covered. For example, in the case of swimming pool, the base frame is placed over the perimeter of the pool. Where a temporary winter shelter is needed, the base frame is placed over the perimeter of a driveway. Or, in the case of a greenhouse, the base frame is placed on an area where the greenhouse is to constructed. These are but a few examples of placement of the base frame.

The base frame can be constructed out of any firm material, such as, but not limited to, wood, plastic or plastic composite, aluminum, etc.

Turning to FIG. 1, at least one embodiment of a bracket (5) is illustrated, composed of a bracket base (10) and a variable-angle member (15) in a position to receive a rib member (30). The variable-angle member (15) is secured onto the bracket base (10), such that the variable-angle member (15) can rotate about an axis parallel to the base (10).

In the embodiment shown in FIG. 1, the variable-angle member (15) consists of a base tubular member (20), attached to a U-shaped bracket (25), which in turn, is attached to the bracket base (10). There are two apertures in the base tubular members (20), which are aligned with two apertures in the U-shaped bracket (25). A screw or similar device, is threaded through all of the apertures, and secured on to the U-shaped bracket (25), but not tightened completely. The variable-angle member (15) is then adjusted to receive one end of the rib member (15). The other end of the rib member (15) is then either attached to another rib member (not shown), or to another bracket, thereby forming a rib. Once the rib is formed, then each longitudinal member is tightened.

The construction of the variable-angle member (15) shown in FIG. 1 is but one embodiment.

The inner diameter of the base tubular member (20) should be slightly larger than the outer diameter of the rib member (30), so as to ensure a tight fit. An optional clamp (35) is attached to the base tubular member (20) for tightening the joint between the base tubular member (20) and the rib member (30).

Alternately, the base tubular member (20) can be constructed as a series of telescoping tubular members, so long as there is angular variation.

FIGS. 2A and 2B respectively illustrate at least one embodiment of a bracket (5) attached to a base frame (40), and a series of brackets (5) attached to a base frame (40).

FIG. 3 illustrates at least one embodiment rib frame, consisting of a series of ribs (45). Each rib (45) is constructed as follows. Once the bracket (5) is attached to the base frame (40), a rib member (30) is inserted into the variable-angle member. Another rib member (31) may then be fitted into the open end of the first rib member (30), and so on, until the assembly of rib members (30, 31) is then fitted into a bracket (6) on the opposing side of the base frame (40). Alternately, a rib (45) may be composed of only one rib member. Where two tubular bodies mate (e.g. bracket and rib member, or first rib member and second rib member), a clamp may be used to secure the mating of the two bodies.

A rib frame, formed by a parallel series of ribs, may be constructed along the length of the area to be covered. The combined rib frame and base frame is called a structural frame. The structural frame can include members in addition to the ribs, to strengthen the structure. In FIG. 4, an additional member (47) is added in addition to the ribs (45).

The strength of the structural frame is high enough to withstand high winds, so that the assembled structure will not be destroyed, nor fall apart, in high winds.

As shown in FIG. 4, once the structural frame is in place, a tarp or sheet (50) is stretched over the rib frame (45), and attached to the base frame (40), to complete the shelter. In order to stretch the tarp (50), and hold it in place, a tarp clamp (not shown) is used.

At least one embodiment of a tarp clamp (60) is shown in FIGS. 5A and 5B. The tarp clamp (60) consists of two longitudinal concentric arcs (65, 70) and a set of screws (80). The tarp (75) fits in between the arcs (65, 70), and is then attached thereto using screws (80), which are secured with conventional means (such as wing nuts, etc). The outer-most arc (70) can have a small aperture, through which a cord (90) is looped. The cord (90) is then used to pull the tarp (75) (via the clamp) over the rib frame (not shown). The cord (90) is then secured to the base frame. With this construction, the tarp (75) does not tear, and withstands weighted objects, as described below.

The longitudinal length of the arcs (65, 70) can vary. The arcs can be constructed from any high-strength material.

The curvature of the arcs can vary as well, as there are no predetermined limits of the curvature.

While a cord is shown in FIGS. 5A and 5B, it is understood that a similar attachment device, such as (but not limited to) a bungee cord, small chain, rope, metal cable etc. can be used to secure the tarp clamp to the base frame.

The tarp (75) can be clear or opaque. It can be UV-resistance. It keeps out dust, and when UV protected, prevents the formation of algae in water (when the shelter is used to cover a pool surface). In addition, the tarp can have a reflective outer surface, to reflect sunlight and heat.

Embodiment Snow Shelter

In cold-weather climates, car-owners are often in need of a temporary shelter to keep snow off driveways. Conventional snow shelters involve wieldy structures.

In one embodiment of the present disclosure, the temporary shelter can be constructed as a snow shelter, as shown in FIG. 6. The shelter (90) consists of a base frame (95), rib frame (100) and a tarp (105). The rib frame (100) consists of a series of ribs (110), constructed of rib members detachably attached to variable-angle members of brackets. Each bracket (not shown) is attached to the base frame (95) on the ground. The tarp (105) is stretched over the rib frame (100), using one or more tarp clamps (not shown), each of which is secured to the base frame (95) with a cord (not shown).

The snow shelter is quick to assemble, and disassemble. To assemble, a base frame is constructed, covering the area to be sheltered. Then, opposing pairs of brackets are attached to the frame, at intervals along the length of the frame. Next, for a given pair of brackets, rib members are inserted between opposing angular members, thereby completing the rib frame. For added security, clamps can be used to secure connections between rib members, and between rib members and variable-angle members. Then, the tarp is prepared by adding one or more tarp clamps onto the tarp, as needed. The tarp (with clamps) is then placed over the rib frame, stretched, and attached to the base frame.

The tarp can be clear or opaque, and is water resistant. The shape of the shelter allows snow to slide off, thereby avoiding dangerous levels of accumulation thereon.

Embodiment Swimming Pool Shelter

FIG. 3 illustrates at least one embodiment of a removable swimming pool shelter, and has been described in detail above.

The tarp can be opaque or clear. It may also be UV-resistant, to deflect UV-rays away from the water, which minimizes and/or eliminates the build-up of algae. This reduces the need of chemicals required to minimize algae production.

The shelter keeps out pollen, leaves, insects, and other debris. It also prevents rodents and small animals from falling in. It also provides safety against small children from accidentally falling in.

This reduces the need for maintenance of the pool, as well as use of chemicals added to the water. In addition, the shelter keeps the water warm, as the heat that rises from the surface of the pool, stays within the shelter (like a greenhouse), and helps to heat the water. In northern climates, the shelter serves to conserve heat, and thereby keeps the pool heated naturally, especially overnight when the temperature drops.

In southern climates, a heat-resistant tarp may be used, so as to deflect heat away from the water surface. Or, a layer of heat-resistant material may be added onto the surface of the water, in conjunction with a regular tarp (which is not heat-resistant). One way to reflect the sun's heat is to use reflective bubble wrap on the surface of the pool. In either case, this prevents the water from over-heating.

The assembled structure has enough strength to keep out children or animals. That is, if either a child or an animal climbs onto the shelter, the tension of the shelter is high enough so that the intruder cannot fall through the shelter, into the pool.

The tarp can be quickly removed, simply by releasing each cord from the base frame. The rib frame can be high enough to permit use of the pool, with, or without the tarp.

The pool shelter can be used in northern climates over the winter, to keep snow and debris out of the pool.
